Passato prossimo with avere
The auxiliary ‘avere’ forms the present perfect; the past participle ‘passato’ does not agree with the object because the direct object follows the verb.
a + infinitive (purpose)
‘a’ introduces an infinitive to express the purpose of the action, similar to ‘to’ in English.
Passare = spend (time)
When used with a period of time, ‘passare’ means ‘to spend (time) doing something’.
Article with ‘notte’
‘la notte’ is a specific time reference; the article is required.

Davvero? Come ti senti adesso?
Really? How do you feel now?
✕Common Mistakes
Passai la notte a studiare.
‘Passai’ is the simple past (passato remoto) and sounds overly literary; learners should use the present perfect ‘ho passato’ in everyday speech.
Ho passato la notte di studiare.
The preposition ‘di’ does not express purpose here; use ‘a’ before the infinitive.
La notte passata a studiare, ho.
While grammatically possible, the usual order is ‘Ho passato la notte a studiare’. Placing ‘la notte’ first can sound awkward in spoken Italian.
↔Alternatives
Ho studiato tutta la notte.
I studied all night.
Ho trascorso la notte studiando.
I spent the night studying.
Ho passato la notte a leggere.
I spent the night reading.
Cultural Tip
Pull‑all‑night study sessions are a common rite of passage for Italian university students before finals. In casual conversation ‘ho passato la notte a studiare’ sounds natural, but in formal writing you might prefer ‘ho trascorso la notte studiando’. Remember that ‘passare la notte’ can also mean ‘to stay overnight’, so context matters.
